摘要:
 研究林分密度对林下植被物种组成和多样性的影响是研究森林结构与功能关系的基础，也是森林经营中林分结构调整技术的基础，为天然林的经营管理和人工林的近自然经营提供依据。试验采用标准地调查法，记录不同林分密度标准地的每个小样方内出现的所有灌木和草本植物种名、个体数，计算各多样性指数并进行分析。结果表明，研究区华北落叶松天然林林下植被物种组成较为贫乏，有灌木8种，草本22种；从不同角度分析草本与灌木物种丰富度对林分密度变化的敏感程度得到的结果不同，从物种丰富度变化幅度上看灌木植物对林分密度的变化较为敏感，而从物种丰富度达到峰值的先后顺序来看，草本植物更为敏感；林下植被多样性对林分密度持续增大的响应表现为非单一变化趋势的规律，随着林分密度的增大，林下植被多样性指数呈现先增大后减少的变化规律，林下植被种类先增多后减少，而均匀度指数呈逐渐下降的趋势；五台山华北落叶松天然林林下植被能在1 072~1 216株/hm2密度范围保持较高的林下物种多样性水平。
Abstract:
 The study of the effect of stand density on the species composition and diversity of undergrowth vegetation is the basis for understanding the relationship between forest structure and function,and also the basis for the adjustment technology of stand structure in forest management,which would be used in the management of natural forest and close-to-nature management of plantations.Methods of recording names and quantities of all shrubs and herbages in quadrat of the standard plots were adopted to calculate and analyze the diversity indexes.The results indicated that the species composition of Larix principis-rupprechtii forest was simple,only 8 shrubs and 22 herbs were recorded.Different results were obtained on the sensitivity of species richness of herbs and shrubs to the changes of stand density from different angles:judging from the change of species richness,shrub plants were more sensitive to the changes of stand density,and from the order of the appearance of peak value,herbaceous plants were more sensitive.The responses of species diversity of undergrowth to the increase of stand density were diverse:with the increase of stand density,the diversity index of undergrowth vegetation increased first and then decreased,the species of understory vegetation had the same variation trend,while the evenness index decreased.The understory vegetation of Larix principis-rupprechtii could maintain a higher species diversity in the density range of 1 072-1 216 /hm2 in Mount Wutai.
